Docker and Laradock Setup Successful Notes (MAC)(WIN)

Docker and Laradock Setup Successful Notes for MAC (tested)(8 GB RAM)
- For windows you might need extra memory more than 4 GB RAM.

My PC Test Specs :
- iMac (21.5-inch, 2017) i5 - 8GB RAM DDR4
- macOS (High Sierra) v10.13.6

Before starting with laradock, make sure you are creating 1 directory

example setup :

+ laraveldocker
+ + laradock (put laradock inside laraveldocker folder)
+ + yourproject_1
+ + yourproject_2
+ + yourproject_3
+ + yourproject_......

// register that laravel folder in docker preferences
right click docker
> Preferences
> File Sharing
> click "+" / Add
> add that folder (laraveldocker)
- - - in my dir is : /Applications/XAMPP/xamppfiles/htdocs/laravel
> Apply & Restart

// install docker
// error notes ? vm cannot be create
// make sure your memory is big enough
// # # and read this notes : https://sharezone47.blogspot.com/2019/05/docker-unable-to-create-ErrorActionPreference.html

// docker compose build (this is the most fatal things in docker)

$> docker-compose 

// docker compose up

$> docker-compose up -d nginx mysql phpmyadmin redis workspace

$> docker-compose up apache2 php-fpm mysql phpmyadmin

$> docker-compose up nginx php-fpm mariadb adminer

// restart every edit laradock

$> docker-compose restart nginx

$> docker-compose restart apache2

// shutdown all docker laradock instance

$> docker-compose down

// to stop docker // example
docker-compose stop nginx

// see running container (docker and docker-compose)
docker ps
docker-compose ps

// edit host os /etc/hosts and add IP/Hostname mapping
127.0.0.1  laravel.test
127.0.0.1  sheezy.local
127.0.0.1  nonlaravelapp.local

// sites nginx

$> cp laravel.conf.example yoursites.conf

// go inside mysql

Docker Unable to create "ErrorActionPreference" (Solved)(Windows)

Come to the New Docker, I get a new error Unable to create: The running command stopped because the preference variable "ErrorActionPreference", and here is the solution (2 solution).

First of all, don't lazy to read the error :

Unable to create: The running command stopped because the preference variable "ErrorActionPreference" or common parameter is set to Stop: The computer 'AKPC-DESKTOP' could not be resolved. Make sure you typed the machine name correctly and that you have network access.

1. If you are seeing "Make sure you typed the machine name correctly and that you have network access"

Solution: you need internet. please turn on your network.

2. After That, Oops we got another error, hahaha. no need to worry.

Unable to execute Start: Unable to create: The running command stopped because the preference variable "ErrorActionPreference" or common parameter is set to Stop: Failed to create the virtual hard disk.

If you are seeing 'Unable to create: The running command stopped because the preference variable "ErrorActionPreference" or common parameter is set to Stop: Failed to create the virtual hard disk.'

Solution :
- open Command Prompt, run as Administrator, then type this one.

MOFCOMP %SYSTEMROOT%\System32\WindowsVirtualization.V2.mof

- Then go to this folder : ( in my place The system failed to create 'C:\Users\Public\Documents\Hyper..... so in your side maybe different. ).

C:\Users\Public\Documents\Hyper-V\Virtual Hard Disks\....

You will see an administrator prompt there. (i forget what, but Windows will show you a Windows to prompt), just allowed that, so all content there can be seen public.

- Finally, run your docker like usual.

- Case Solved

More info  :
- Docker not starting on windows 10 #214
- Unable to create: The running command stopped because the preference variable "ErrorActionPreference" #1538
- Can't run Docker for Windows after install for the first time #1177

Docker for windows (BASIC guide)

What is docker ? and why docker ?
one bad day for dev is that "wait, this work in my machine"

So, to prevent that we use docker

String - character length and size - C++

Compiler online :
http://cpp.sh/

//Code to learn:

#include<stdio.h>
#include<iostream>
using namespace std;
int main()
{
   char a[5]="abc";
    cout<<sizeof(a);
    cout<<endl;

    string s;
    s=a;
    cout<<s.length();
    cout<<endl;
    cout<<s.size();
    cout<<endl;
//other output type
    cout<<"String = "<<s.size()<<endl;
    cout<<"Size of string :"<<s.size()<<endl;
    cout<<"Size of string :"<<s.length();
    return 0;
}
